Liked the idea of coil inside the tube but found it frustrating to try to seal the PVC jacket. Went to copper X copper exchange with coil on the outside of the water jacket - this was close but did not get the amountof heat transfer i had hoped for. This final model is 4' of 2" copper with 24' of 1/4" copper fabricated as a home-made coil - inserted inside the 2" as shown. A slight modification to my closed water loop is needed to accomodate the larger model but all is looking good so far
